The Huber function https://en.wikipedia. org/wiki/Huber_loss is defined as: f (I ) = if I 1 The Huber function is quadratic in the interval [-1, 1] (red line in the figure below) and linear outside the interval (blue line in the figure below). The transitioning between these two curves is smooth as you can be verified by taking derivatives. Huber 3.0 2.5 6 20 fix) 2 05 0.0 -2 -1 0 IN 1.
